What do you think this means?

My boyfriend of 7 months was lying in bed with me the other day, and just started mindlessly talking to me. He told me that I made him feel "warm" and "at home." What do you think those two things mean? Are they just kind of fluffy phrases that don't mean anything specific and they just feel right, or is it the kind of thing that would vary from guy to guy? what would you mean if you said all of that? it sounded to me like it was all positive, but I can't figure out exactly what those two phrases mean, especially "at home."Thanks!
